Easily attach nanoparticles like toy blocks for industrial use!

Dr. Yu’s team at KERI has developed a dry-process technology for synthesizing hybrid supraparticles, inspired by lunar craters, with expectations for applications in a wide range of industries; featured as an Inside Front Cover in Advanced Materials.

2025-06-17
(Press-News.org) Dr. Seunggun Yu and his team at KERI's Insulation Materials Research Center have developed a groundbreaking ‘Hybrid Supraparticle Synthesis Technology’ that can attach inorganic nanoparticles to the surface of polymer microparticles through simple mechanical collisions.

The ‘Hybrid Supraparticle Synthesis Technology’ that combines functional inorganic nanoparticles with polymer microparticles is being widely applied across various industries, including battery electrode materials, catalyst systems, pharmaceuticals and biotechnology, semiconductor packaging, and insulating materials for electrical equipment. In this process, materials are primarily combined through wet chemical processes, which pose several issues, including ▲complex multi-step procedures and additional costs, ▲environmental problems due to the use of solvents, and ▲limitations in surface functionalization technologies required to induce chemical bonding between different materials.

Inspired by the craters formed on the Moon due to asteroid collisions, Dr. Seunggun Yu introduced a method of physically and mechanically colliding particles. In this process, inorganic nanoparticles were individually attached to the surface of polymer microparticles, forming a core-shell structure where the nanoparticles envelop the polymer microparticles like a shell.

Although this may seem like a simple principle, its actual implementation was very challenging. In order for the nanoparticles to be stably attached to the surface of polymer microparticles, various factors must be considered simultaneously, including the size ratio between the particles, collision speed and rotational energy, surface energy, and roughness. By precisely controlling these conditions, Dr. Yu’s team successfully combined dozens of different inorganic nanoparticles with microparticles of varying sizes and properties, establishing the optimal synthesis conditions. They also succeeded in uncovering the physical attachment mechanism, marking the world's first discovery of this process.

In addition, the research team developed a technology to quantitatively analyze the degree of nanoparticle attachment, surface coverage, and the stability of the interface bonding, while also evaluating the thermal, mechanical, and chemical durability. Through this, they were able to obtain multifunctional, high-reliability composite particles with excellent resistance to various environmental conditions, while simultaneously possessing magnetic, photocatalytic, and adsorption properties..

The research findings have been recognized for their excellence and were published as a inside front cover in Advanced Materials, one of the top journals in the field of materials science. The journal's impact factor, which is used to assess the quality of the paper, stands at 27.4, placing it in the top 1.9%.

Dr. Seunggun Yu stated, "Since we can easily combine the materials we need like toy blocks in an eco-friendly dry process that uses no solvents, it is advantageous for mass production and commercialization." He also mentioned, "This technology has a very wide range of attachable materials, and the reproducibility in a simple process is high, which means the entry barrier for the industry is very low."

KERI aims to accelerate the optimization of ynthesis processes through continuous research. In addition, it plans to actively pursue commercialization by identifying potential industry partners interested in the technology and promoting technology transfer.

The KERI(Korea Electrotechnology Research Institute) is a government-funded research institute under the NST(National Research Council of Science & Technology) of the Ministry of Science and ICT. This research was conducted as part of KERI’s core program, in collaboration with Professor Dong Woog Lee’s team at UNIST, Dr. Seung-Yeol Jeon’s team at KIST, and Professor Shu Yang’s team at the University of Pennsylvania.

LEGO improves maths and spatial ability in the classroom

2025-06-17
A simple classroom activity involving a classic childhood staple, LEGO, could improve children’s maths and spatial ability, leading researchers to demand for policymakers to shake up the school curricula and teachers’ professional development.  A new study, led by the University of Surrey, tested incorporating LEGO building into the daily teaching curriculum, leading to tangible improvements and boosting abilities for students aged six to seven.   The study, which involved 409 children from schools in Surrey and Portsmouth, demonstrated ...

Despite overall progress, low birthweight rates still high in certain Indian states

2025-06-16
Despite overall progress in bringing down low birthweight numbers across India over the past 30 years, rates remain stubbornly high in certain states, with Uttar Pradesh, Bihar, Maharashtra, and West Bengal, accounting for almost half of all such births, finds research published in the open access journal BMJ Global Health. Low birthweight is important, because it often signals underlying maternal health issues and poor nutrition as well as the child’s future cognitive development and susceptibility to chronic conditions in later life, note ...

Train teachers on how to get parents involved in children’s learning, say researchers

2025-06-16
Over half of primary and secondary school teachers in England have not been trained in how to support parents’ involvement in children’s learning and education at home and at school.     That’s according to research published today in the peer-reviewed journal Educational Review, which is a first study of its kind based on a survey of more than 1,700 teachers reveals concerning gaps in skills.    Led by academics from the University of Warwick and UCL, the paper shows teachers’ essential pre-qualification training fails to ...

Long-term study reveals Native seeding controls annual, but not perennial, invasive plants in sand grassland restoration

2025-06-16
The HUN-REN, CER-IEB Restoration Ecology Research Group monitored vegetation changes over 17-25 years across eight restoration sites, subject to different restoration interventions: seeding with native species, mowing, and carbon amendment. The goal was to understand how these treatments influence the abundance of annual and perennial invasive alien plants over time, and how abundance of invasive species in a 100 m buffer affects invasion dynamics at restoration sites. The results were promising for annual invaders. In most cases, their cover declined over time, especially when native seeding was applied. Seeding proved to be the most ...

Exposure to low levels of arsenic in public drinking water linked to lower birthweight, preterm birth, study finds

2025-06-16
Babies born to mothers potentially exposed to low levels of arsenic in public drinking water—even at levels below the federal safety standard—were more likely to be born preterm, with lower birthweight, or be smaller than expected, according to a study funded by the National Institutes of Health’s Environmental influences on Child Health Outcomes (ECHO) Program. While the U.S. Environmental Protection Agency sets a maximum contaminant level of 10 micrograms per liter for arsenic in public water systems, this study examines how even lower-level arsenic exposures may still affect pregnancy outcomes in a large population. Previous research ...
